Technical Beauty Comes Around: A Retrospective of the Ulysse Nardin Freak
When the brand unveiled the Freak in 2001, it fomented a revolution on three fronts — design, mechanical and material — while being steeped in tradition. Its original design came from Carole Forestier-Kasapi, who saw the tourbillon as an entirely new way of displaying time. In fact, her concept of having a revolving movement surrounded by a giant mainspring had earned her the winning prize at the Prix de la Fondation Abraham-Louis Breguet in 1997, most notably beating the English watchmaker Derek Pratt who had just been the first to put a natural escapement in a tourbillon watch. Under the direction of Dr. Ludwig Oechslin, a Vatican clock restorer, her proposal eventually underwent a complete reconfiguration. Among other things, he relocated the mainspring to the back of the watch beneath the gear train, giving it a week’s worth of power reserve.

With neither hands, a dial nor a crown, the Freak upended all notions of how watches and movements were designed, becoming the first watch with a movement that expressed time independently
Prior to the Freak, watchmaking was a repository of age-old traditions and watches served only to emotionally connect us to those said traditions. They were generally constructed in a two- dimensional manner with the mainspring and balance occupying the same plane at the edges of a base plate, which is topped by a dial that is swept over by hands. The Freak, however, shocked the world in the way it defied and reconfigured centuries-old norms and brought an intellectual depth that only wonder-and- awe innovations can provoke. It lacked a proper dial, or hands for that matter; instead, mounted on a huge mainspring barrel was a linear gear train that made a complete revolution once per hour, doubling as the minute hand of the watch.

The Freak was also the first wristwatch to incorporate a natural escapement which unlike any other escapement, delivers both direct and dual impulse to the balance wheel at each cycle
The properties of silicon have rendered it an extremely beneficial material for watchmaking. Being a third the density of steel, it operates with low inertia, meaning the amount of energy required to move a silicon component is far less, thus allowing a movement to run with greater efficiency. Secondly, it is harder than steel and has a completely smooth surface, allowing interacting components to work together without the need for lubrication and with insignificant surface wear over time. Thirdly, it can be fabricated with extreme precision and in complex geometries through DRIE, with no further intervention after they have been formed. Fourthly, it is also highly elastic and therefore, shock- resistant as it is capable of bouncing back to its original shape immediately upon impact. Last but not least, it is also anti- magnetic, counteracting the effects of a long-time foe.
The first silicon escape wheels were produced for Ulysse Nardin by Centre Suisse d’Electronique et Microtechnique (CSEM), a Swiss research institute that specializes in micro-electromechanical systems (MEMS). More than that, the Dual Direct Escapement in the Freak ingeniously integrated Breguet’s two-level escape wheel construction into a single plane. Each escape wheel has 25 teeth with every fifth tooth protruding slightly with a pointed tip while the rest have flat tips. The teeth with flat tips serve to drive the next escape wheel and the pointed tips contact a pivoting stopper that delivers an impulse directly to the balance wheel at each vibration.
Freak 28’800 V/H: The Evolved Freak [2005]

The Freak 28’800 V/H saw the introduction of the Dual Ulysse Escapement characterized by improved geometry of the escape wheels.
The new escapement featured 18 identical teeth with hooked tips resembling shark’s teeth that nested on the edges of the revised stopper, as opposed to the first generation’s 25 teeth per escape wheel, five of which extended to engage the stopper. Because all the teeth are now functionally contacting the stopper, it resulted in a reduced sweep angle per tick, therefore a more stable mechanism. And since it required less time to revolve at this smaller angle, the new movement could accommodate a high frequency balance, hence the increase from 3Hz to 4Hz, or 28,800vph, giving rise to the model’s name.
Additionally, the annular balance wheel was also replaced by a free-sprung balance with four adjustment screws recessed into its periphery and a silicon hairspring. Apart from the escapement, the Freak 28’800 V/h also introduced a locking tab to prevent the bezel from turning inadvertently.

Subsequently, in 2006, Ulysse Nardin embarked on a joint enterprise with Mimotec and founded Sigatec, a manufacturer that specializes in both DRIE for silicon parts and LIGA (Lithographie, Galvanoformung, Abformung) for metal parts, enabling them to produce precision components that were light, corrosion resistant and nonmagnetic on an industrial scale and make them available to the rest of the industry.
Freak Diamonsil: The Advanced Freak [2007]

The Freak DIAMonSIL of 2007

The result was exhibited in the Freak DIAMonSIL in 2007 which featured a Ulysse Dual Escapement made of DIAMonSIL. With the new material, the escapement reached its height, offering both high efficiency in energy transmission and a surface hardness that was practical for longevity.
Innovision 1: The Radical Freak [2007]

The InnoVision 1 was a visionary Freak that demonstrated the tremendous potential of silicon in all aspects of movement design
Most notably, the concept watch also saw the introduction of three-dimensional silicon components. In its infancy, silicon parts were mostly etched as flat, planar parts. But the most crucial bits of the oscillator in the InnoVision 1, namely the escapement stopper and security pin, the balance roller and impulse pin as well as each escape wheel and its pinion were each fabricated in silicon as a single unit with two levels respectively. In addition to being able to be manufactured to extremely fine tolerances, these multi-function single components also reduced assembly time.
Freak Diavolo: The Complicated Freak [2010]

Typically, with the addition of a tourbillon cage, inertia and frequency are necessarily compromised to power and make room for the cage. To put things into perspective, the workhorse ETA 2892, which is not a tourbillon and hence does not have to overcome the additional inertia of a cage, boasts the exact same inertia and frequency. This speaks to the benefits of the Freak’s inherent architecture that can accommodate a strong mainspring, while the use of silicon in the escapement helps reduce inertia to ensure more efficient power transmission to keep the balance wheel oscillating.
Bringing more utility to the watch, the tourbillon cage also doubled as the seconds hand, which can be read against a semi-circular seconds bridge.
Freak Cruiser: The Seagoing Freak [2013]

The Cruiser also saw one of the most appreciable aesthetic improvements in terms of the movement. The bridges for the gear train and balance wheel were now sleeker with a slim, skeletonized anchor-shaped design that no longer obstructs the view of the gear train.
FreakLab: The Calendrical Freak [2015]

The FreakLab was the first Freak to introduce a date indication
The date wheel of the FreakLab is visible through an aperture at four o’clock. As the crown and winding stem remained absent in the watch, the date is set by turning the bezel counter-clockwise, while time is set by rotating the bezel in the clockwise direction. Notably, the balance wheel was now positioned at the center of the watch, allowing it to closely resemble a typical minute hand. However, the fundamental architecture of the movement remained unchanged.
Further in, the brand continued to showcase its expertise in fabricating silicon components with the introduction of its own silicon shock protection system, dubbed the UlyChoc. While a typical Incabloc shock absorber system consists of a setting, a chaton, a balance staff jewel, cap stone and anti-shock spring, the UlyChoc incorporates a silicon spring around the chaton that houses the jewel and cap stone. Upon impact, the elasticity of silicon allows the chaton to move in its setting to absorb shock but re-centers it immediately.
Innovision 2: The Freakiest Freak [2017]

With the use of cutting-edge materials and technologies, the InnoVision 2 was a hyper Freak that pushed the limits of what is possible in watchmaking
Among its 10 innovations was the Dual Constant Escapement. It operates on the same principles as a natural escapement but with the added benefit of delivering constant force to the balance wheel, regardless of the mainspring’s state of wind. This is made possible by constructing the escapement as a compliant mechanism which would use the elasticity of silicon to perform its mechanical function.
The Dual Constant Escapement comprises of a single silicon frame of an intricate shape with an integrated pair of blades that flex between fixed ends when tensioned alternately by the escape wheels, ensuring a very precise and consistent transmission of energy at each vibration.
The InnoVision 2 also saw the introduction of a silicon balance wheel that was combined with four adjustable gold weights on its periphery to achieve an ideal mass-inertia ratio. Being extremely light, the balance wheel incorporated micro-blades between its spokes to minimize air resistance.

Other exotica in the watch included a sapphire-coated silicon bridge, glass bridge with integrated shock protection for the balance wheel as well as Super-LumiNova filled channels that were integrated into the glass balance wheel bridge.
Freak Vision: The Futuristic Freak [2018]

The Freak Vision brought some of the most crucial advancements in the InnoVision 2 to a commercial reality while being the first Freak to have its entire gear train etched from silicon
The Dual Constant Escapement was replaced by the tried-and- tested Ulysse Anchor Escapement that was launched in 2014. It consists of a circular silicon frame that holds the lever in place. Instead of a pivot, two perpendicular, buckled blades of silicon on both sides of the frame converge at the pivot point of the lever. The buckled blades flex between fixed ends, providing a precise and constant flow of energy to the balance regardless of the torque from the mainspring.
The silicon gear train is held in place by a pair of skeletonized, delta-shaped central bridges that were inspired by the hull of a boat, giving the movement a lighter, airier appearance. Although the Freak Vision has a large diameter of 45mm, it was an exercise in practicality and elegance. The dramatic fluted bezel design was replaced by one that was circular and flat with three titanium riders for time-setting.
Freak Out: The Retrospective Freak [2018]

The Freak Out was a combination of all of the most desirable attributes in the Freak’s lineage
As a result of being made in titanium, the Freak Out was the most affordable Freak that kept all the iconic mechanical characteristics of the original. At the same time, both the uniform matte finish across the case and the redesigned bezel with a series of widely spaced double notches ensure that nothing detracts from the visually spectacular movement.
Freak X: The Daily Freak [2019]

The Freak X reprised the baguette-shaped time display that made the Freak a freak while introducing meaningful implements such as a user-friendly crown, a reduced case diameter of 43mm and a high-tech silicon balance wheel.
It abstracts the very essence of the Freak, namely an orbital oscillator and a silicon escapement, and realizes it in a more traditional automatic movement, which enables hand winding and setting via a traditional crown. The automatic caliber UN-230 inside is based on the brand’s workhorse automatic cal. UN-118 but with a module integrated in the baseplate. Visible on the dial, the module consists of a planetary gear system, made up of a large, fixed gear ring, a planet gear for the hour hand, and a central gear for the minute hand. While the rest of the gear train remain hidden, the escapement and balance wheel form the minute hand, completing a full rotation in an hour.
Freak NeXt: The Otherworldly Freak [2019]

Instead, the balance wheel is made up of four stacked silicon wheels, each fitted with eight micro-blades, with every pair forming a triangle. The entire balance wheel is secured to the movement with screws at two points and does not have a pivot, hence it operates without friction. The balance is impulsed by the Ulysse Anchor Escapement which also does not have a lever pivot and relies on the flexibility of silicon to deliver consistent energy throughout the course of its power reserve.
Additionally, the gear train is also made of silicon, reducing friction and wear. The performance gains in all these areas, namely low inertia and friction, enables the oscillator to operate at a dramatically high frequency, making it the most visually dynamic Freak. It is also equipped with the Grinder automatic winding system that consists of a peripheral rotor and a circular frame with quadruple winding pawls, which engage a central wheel that winds the mainspring.
Freak S: The Chronometric Freak [2022]

For lovers of the Freak who wanted its visual effect squared, the Freak S boasted not one but two inclined balance wheels with their differences in rate averaged out by a full-fledged vertical differential.
Freak ONE: The Freak that bridges the past to the future [2023]

The Freak ONE is the culmination of the most celebrated design elements and technological advances throughout the Freak’s evolution.
Although it relies on a traditional lever escapement, both the escape wheel and pallet fork have been fashioned from DIAMonSIL. In fact, it represents the first time this configuration has been employed; the lever escapement in the Freak X, for instance, was executed in silicon. Hence, it not only avoids the primary flaw of the Swiss lever escapement, enabling it to operate virtually frictionlessly without the need for lubrication but is also endowed with greater strength and resilience to withstand the test of time. It is paired with a lightweight but oversized balance wheel made of silicon. Notably, the Freak ONE has a frequency of 3Hz, which is slightly higher than that of the automatic Freak Vision and is also equipped with gold adjusting weights instead of nickel. All things equal, a high-power balance wheel maintains more stable timekeeping as the balance is less susceptible to shocks caused by wrist motions. The gear train is held in place by lean and clean bridges colored in rose gold, offering maximum visual access to the parts while providing superb legibility.

It combines a DIAMonSIL escapement with an oversized balance wheel made of silicon.

In other words, it is a watch for the Freaks in all of us.
